Correct Option: C

Ribosomes are the workhouses of protein biosynthesis, the process of translating messenger RNA (mRNA) into protein. The mRNA comprises a series of codons that dictate, to the ribosome, the sequence of the amino acids needed to make the protein. Using the mRNA as a template, the ribosome translates each codon of the mRNA, pairing it with the appropriate amino acid. This is done using molecules of transfer RNA (tRNA) containing a complementary anticodon on one end and the appropriate amino acid on the other.Protein synthesis begins at a start codon near the 5’ end of the mRNA.
